Plants small to large, creeping or in loose mats, brownish green, dull to somewhat shiny. Stems irregularly branched or sympodial; primary stems creeping, branches spreading to pendent; secondary stems erect-ascending or rarely pendent, not or little branched, branches short to elongate, terete-foliate, simple or branched; paraphyllia and pseudoparaphyllia absent or present. Leaves spirally inserted, imbricate, spreading when moist, ovate-acuminate, concave; margins entire or sometimes serrate distally; apex usually acute; costa single; alar cells rounded to quadrate; medial laminal cells rhomboidal to fusiform, smooth to prorulose. Sexual condition autoicous or dioicous; perigonia axillary, gemmiform; perichaetia lateral or terminal on branches, gemmiform. Seta single, very short or barely exceeding perichaetial leaves. Capsule erect, immersed to barely exserted, symmetric; stomata few, proximal; annulus revoluble; operculum conic-rostrate to obliquely rostrate; peristome usually double, (pale); exostome teeth 16, papillose; endostome usually rudimentary, segments 16, linear, or absent, cilia absent. Calyptra mitrate or occasionally cucullate, smooth or papillose. Spores spheric, granular to papillose or sometimes smooth.
